Last updated 8 September 2026. FounderProof Advisory is a trading name of JCS Advisory Limited, registered in Ireland, company number 816874, registered office 27 Cork Road, Midleton, Co. Cork, P25 K162.
JCS Advisory Limited, trading as FounderProof Advisory (“FounderProof”, “we”), is the data controller for personal data collected through this website and in the course of our work. You can reach us at calvin@founderproof.com or at the registered office above.
When you book a call, take the free self-assessment or use the contact form, we collect the details you give us — typically your name, company, work email, approximate revenue and what you tell us about your business. We use them to reply to you, to prepare for and hold the call you asked for, and to send the written view you requested. Our lawful basis is that we are taking steps at your request before entering a contract, and our legitimate interest in responding to enquiries about our services.
If you become a client, we process the personal data needed to deliver the engagement — contact details of your team and, where your systems contain it, data about your customers. We act on your written instructions under the engagement terms, with a confidentiality agreement in place before we are given access.
We do not add you to a newsletter or automated sequence because you enquired. We do not sell or share personal data with third parties for their own marketing. We do not use tracking for advertising on this site.
A small number of providers process data on our behalf to run the website and our systems: Webflow (website hosting and form submissions), HubSpot (meetings scheduling, CRM and email), Google Workspace (email, documents and file storage) and e-signature and accounting providers for contracts and invoicing. Some of these providers store data outside the European Economic Area; where they do, transfers are covered by the European Commission’s adequacy decisions or standard contractual clauses.
Enquiries and self-assessments that do not lead to an engagement are kept for up to 24 months so we can pick up the conversation if you come back, then deleted. Client records are kept for the duration of the engagement and for six years afterwards to meet legal and accounting obligations. Access to client systems is removed at the end of every engagement.
You can ask us for a copy of the personal data we hold about you, ask us to correct or delete it, restrict or object to how we use it, or ask for it in a portable format. Email calvin@founderproof.com and we will respond within one month. If you are not satisfied, you have the right to lodge a complaint with the Data Protection Commission (dataprotection.ie) in Ireland or, for UK residents, the Information Commissioner’s Office (ico.org.uk).
This site uses only the cookies needed for it to work and for Webflow to process form submissions. We do not run advertising or cross-site tracking cookies.
We will update this notice when our practices change and show the date at the top. Questions about this notice go to calvin@founderproof.com.
